OSTEOPATHIC TABLE.

Application filed May 17, 1915.

T 0 aZZ whom it may concern Be it known that I, JOHN V. MoMANIs,

a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Osteopathic Tables, of which the following is a specifi cation.

My invention relates to operating tables and more particularly to such tables which are adapted for osteopathic practitioners use. The object of my improvement is the provision of a simple and efficient construction whereby portions of the table top may be easily and quickly adjusted to desired positions and locked in such positions. Other objects will appear hereinafter.

I have shown an embodiment of my invention in the accompanying drawings, in which Figure 1 is a plan view of an operating table embodying my invention; Fig. 2 is a side elevation of the same; Fig. 3 is an end elevation of the same, and Figs. 4:, 5 and 6 are enlarged fragmental sections taken on lines 4%, 55 and 6--6 respectively, of Fig. 2.

Referring more particularly to the drawings, I provide a supporting stand 6, or pedestal, upon which are mounted the table top sections and the parts adapted to control theirmovements. At one side at the top of the pedestal I provide a projection 7 upon which is secured the main table section 8. The pedestal is preferably of metal but may be made of any desired material. 'lhe main table section 8 may beof wood or any preferred substance having an upholstered top 9 of any approved construction.

The pedestal 6 is provided with two cars 10 spaced apart and having perforations therein. In the perforations of the ears 10 is mounted a post 11. The upper portion of post 11 is preferably round where it passes through the cars 10, but has its lower end 12 formed square with rack teeth 13 formed in one side thereof. The rack teeth 13 preferably do not extend entirely across the face of one side of the post thereby leaving a plane surface 14 on the same side with the rack teeth providing a locking surface against which a cam 15 operates. The cam 15 is mounted on a shaft 16 and the latter carries a manually operable crank 17 by means of which the cam 15 is operated.

Specification of Letters Patent.

Serial No. 28,532.

The face of cam 15 is so cut that downward pressure on shaft 11 looks the latter against downward movement while upward movement of the post causes the cam to free itself from looking engagement with the surface 14, as will be readily understood upon reference to Fig. 2. The shaft 16 is mounted in an ear 18 on the pedestal 6.

In order to facilitate movin the post 11 vertically I provide mutilated gear 19 which is mounted on a shaft 20 and the latter journaled in an ear 21 on base or pedestal 6. The shaft 20 carries a manually operable crank 22 which facilitates operating the gear 19 to move the shaft 11 vertically.

On the upper end of shaft 11 I provide an intermediate table section 23 having a base casting 24 and the latter pivoted on the upper end of the post 11 for horizontal swinging. I preferably form one side of the intermediate table section 23 circular and concentric with the axis of the post 11 so that such curved edge of the intermediate table section will fit into the similar curved edge 24: of the main table section 8. In order to lock the table section 23 at various points in its lateral swinging on post 11 I provide a lock 25 which may be a handled set screw, such as shown, or any other suitable means.

A bracket or hinge member 26 is provided with cars 27 and the latter perforated and pivoted on post 11 so that the member 26 may swing about the axis of post 11. In order to maintain the member 26 in its normal position, namely, in substantially alining position with intermediate table section 23 and main table section 8, I provide arms 28 on one of the ears 27 and secure the ends of tension springs 29 thereto. The other ends of the tension springs 29 are secured as at 30 to pedestal 6 so that the springs 29 will produce a resilient restraining means tending to hold the member 26 in said normal position. In order to lock the member 26 against pivotal movement about post 11 I provide a lock 31 which may be a handled set screw or any other preferred lock (see particularly Fig. 6).

To the upper portion of member 26 I pivot an arm 32 as at 33 for vertical swinging. Concentric with the point 33 is an arcuate slot 34:, and passing through the slot 34c is a screw 35 having a manually operable handle 36 secured thereto. The

arrangement is such that upon pivotal movement of arm 32 to different positions about arm 33 the screw 35 may be manipulated by the handle 36 to lock the arm 32 in any desired point of such pivotal movement.

Arm 32 is provided with a rectangular portion having parallel sides 37 and end portions 38. Intermediate of the end portions 38 is an upstanding connecting portion 39. The portions 38 and 39 extend upwardly above the portions 37 and are provided with alining perforations 40 in which is journaled a shaft 41. Journaled in one of the portions 38 and portion 39 is a shaft 42 having a threaded portion 43 at one end threaded in a slidable member 44 mounted on the members 37. The other end of shaft 42 is provided with a hand wheel 45 by means of which the shaft 42 is manually operated. At the other end of arm 32 is a shaft 46 slidably mounted in the other of members 38 and a slid-able member 47 mounted on members 37 Between the memshaft 41.

bers 44 and 47 is a compression spring 48 tending to press the shaft 46 away from shaft 42. The shaft 46 carries a friction roller 49 at its outer end which rides on a cam 50 on member 26. The shape of cam 50 is such that upon weight being applied to arm 32 the wheel 49 will ride over the cam 50.

The shaft 41 is provided with threaded portions 51 threaded in upstanding supports 52. Each of the members 52 has a downwardly extending arm 53 which engages one of the shafts 42 or 46 in order to prevent rotation of the members 52 on the One of the members 52 is pro vided with a clamp portion 54 which is operated by a hand screw 55 to clamp the member 52 on the shaft 41 to prevent rotation of the latter, thereby preventing longitudinal movement of the members 52 on the shaft 41.

Each of the members 52 is provided with a perforation 56 in which is mounted a curved track 57. A locking screw 58 is threaded in each of the members 52 to lock the track members 57 against longitudinal movement in the perforations 56. On the ends of the members 57 is mounted an auxiliary table section 59. The upholstering on main table section 8 intermediate table sec tion 23 and auxiliary table section 59 is preferably similar, both in construction and material and may be of any preferred material and construction.

It will be noted from the construction set forth that the auxiliary table section 59 may be moved longitudinally thereof away from and toward the intermediate table section 23 by loosening lock screw 55 so that shaft 41 may be rotated and then operating the latter by means of'a crank 61. The hand wheel 45 may be operated to increase or decrease the tension on spring 48 thereby providing means for accommodating different weights on the auxiliary table section 59. The cam surface 50 is so designed that upon the weight being increased on table section 59 the downward movement of the auxiliary table section will be less than the propor tionate added weight since the tension on spring 48 increases as the movement of auxiliary table section increases downwardly.

It will be noted that intermediate table section 23 is capable of being lowered to a height so that it may swing under the corners of the auxiliary table section 59, if so desired, or the auxiliary table section may be swung on post 11 sothat its corners will pass over the intermediate table section 23, if desired. Also when the intermediate table section 23 is moved upwardly above the other table sections it is capable of being swung over the auxiliary table section 59 or the auxiliary table section 59 may be swung under a portion of the intermediate table section 23. Advantages of these different movements will be apparent to practitioners. It will also be noted that the intermediate table section 23 and auxiliary table section 59 may be locked in all of their various positions of movements by means of the locks 25, 31, 35 and 55. The position of pivotal point 33 is such that the end 62 of the intermediate table section 59 will not be raised materially above the upper level of its position shown in Fig. 2 and main table section 8 whether the auxiliary table section 59 is moved upwardly or downwardly on said pivotal joint. It will be further noted that in rocking the auxiliary table section 59 on the tracks 57 in the perforations 56 that such table section will remain substantially in alinement with the other table sections. This is accomplished since the axis of the table section is substantially on a level with the top thereof and longitudinal therewith.
